  • Patent number: 9595629
    Abstract: An optical device is formed from a device precursor having a layer of a light-transmitting medium on a base. A first feature is formed on the device precursor. The device precursor is then processed such that a stop layer protects the first feature and a portion of the device precursor is above the top of the stop layer. The first feature is between the base and the stop layer. The device precursor is planarized such that the portion of the device precursor located above the top of the stop layer becomes flush with the top of the portion of the stop layer that is present on the device precursor after the planarization. During the planarization, the stop layer acts as a planarization stop that slows or stops the rate of planarization.
